DOMENICK RUFF, OF .YOUNGS'I'OWN, OHIO.

SAFE PROTECTOR.

Application filed July 18, 1924. Serial No. 726,848.

To all whom it may concern:

Be it known that DOMENICK RUrr, citizen o l the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, has invented certain new and useful Improvements in Safe Protectors, of which the-following is a specification.

This invention relates to a device for preventing unauthorized tampering with or opening of safes, locks, doors, etc.

The principal object is to provide an attachment to be put on the safe door or built in a regular equipment of a safe, comprising a primary and a secondary gas chamher, so arranged that when an unauthorized attempt is madeto disturb the locked condition of a safe, this gas will be released.

The gas which may be used will depend upon the judgment of the person using the same or so that a complete compliance with t he regulations of law may be complied with. Tt is suggested that the gas to be used may be of the most deadly nature or gases known as tear gas, sneezing gas, and gases which have a peculiar effect but not resulting in serious physical in jury.

The drawing illustrates a preferred embodiment of the invention. However, it is to be understood that in adapting the same to meeting different conditions, various changes in the form, and minor details of construction may be resorted to without de parting from the nature of the invention as claimed and set forth in the drawings Figure 1. is a front elevation of a portion of a safe door, with device attached.

Figure 2 is a cross section taken on line 11 of Figure 1.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by like reference characters.

By referring to the drawing, it will be seen in the several views of the drawing, Ihave provided a circular chamber 1 which is delicately secured to an outer portion 2 of a safe door, by means of screws 3. This circular chamber 1. is provided with a flattened base portion 4: fitting against the outer portion 2. By referring to Figure 1, itv will be seen that this circular chamber 1 is placed so as to surround a dial 5 having a central knob 6 which is the outer end of lock shaft 7. Attached to this circular chamber 1, is a frail tube 8, communicating with T-connect-ion 9. This Tronnection 9 is fitted with an upwardly extending tube 1.0 provided with a valve 11 which is connected to an upper gas chamber '12. There is secured to the lower portion of the T-connection 9, a tube 13 made of relatively frail material and having a solid end 14, over which fits a heavy depending rod 15 which is held in place by means of a cotter pin 16, which passes through the upper portion 17 of the heavy depending rod 15, and through the solid end 14.

The upper gas chamber 12 may be equipped with any ordinary intake valve 18 such as used in loading or filling gas chambers, or the upper gas chamber 12, may be filled through the valve 11. It will also be seen that the circular chamber 1 will also be filled when the valve 11 is open, or through valve 19.

If desired, the upper gas chamber 12 may be eliminated and the gas used confined only to the circular chamber 1.

Persons attempting to open a safe in an unauthorized manner often use a hammer or sledge and break of the central knob 6 carrying the dial 5. When this central knob O has been removed, the burglar then drifts the safe by using a punch and driving the lock shaft 7 inwardly. If this manner of breaking into the safe is attempted on a safe equipped with my device, the circular chamber 1, which is secured to the safe door insecurely, will easily yield to force. When this circular chamber 1 has been broken away from its holdings, the tube 8 is sheared or broken and causes an exit for the gas or gases contained in one or both of the gas chambers.

In the event, however, the central knob 6 is removed by drilling or other means without disturbing the circular chamber 1 and the lock shaft 7 driven inwardly, this shaft will force the heavy depending rod 15 inwardly thereby fracturing or breaking the tube 13, resulting in making an exit for the gas or gases. A set screw 20 holds the heavy depending rod 15 in desired relation with the lock shaft 7.

What I claim is 1. In a device of the class described, the combination of a circular chamber posi ioned around a central knob carrying a dial, means for securing said circular chamber to the outer v surface of a safe door, an upper gas chamber, and a frail tube communicating with Stld circular chamber and also communicating with said upper gas chamber, substantially as described for the purpose set. forth.

2. In a device of the class described, a circular gas chamber positioned on the outer surface of a safe door and surrounding a central knob and dial, a tube communicating 5 with said circular chamber, a tube leading to an upper gas chamber, a valve between the tubes of said gas chambers, a frail depending tube with upperend communicating with said gas chamber and having a solid end, a heavy depending rod attached to said frail 10 tube, said heavy depending rod positioned directly back of the lock shaft, substantially as described for the purpose set forth.

In testimony whereof I aflix my signature.
